Is there a way to limit the grid to just where you want the 2D drawing to be, say the selected paper size limits? This ability to zoom forever is driving me crazy. I cannot just zoom in and have it keep the grid units constant.
I zoom in to get more resolution and presto change, the grid suddenly redoes itself and I have no idea what the scale is any more.
At the bottom of the screen (status bar) you find 'Grid Status'.
Distance of grid points / grid lines, so this gives the scale.
In Options - Application preferences - Appearance there is 'automatically scale grid', however it doesn't seem to have any effect to deselect it. Maybe you can find out.
"And can I limit the grid to just the area of the drawing?"
I have found it useful to first draw a frame in the size of the intended paper sheet (according to the intended scale). With 'autozoom' or doubleclick on the middle mousebutton/wheel you instantly get an overview of the drawing, so you are not lost in space.
You can easily make templates for different drawing/paper sizes and scales, and also incorporate the appropriate dimensioning settings.
